Three-dimensional motion of a viscous incompressible fluid in a narrow tube
A. E. Medvedev Khristianovich Institute of Theoretical and Applied Mechanics, Siberian Division, Russian Academy of Sciences, Novosibirsk, 630090, Russia
Abstract:
An approximate solution of the problem of unsteady motion of a viscous incompressible fluid in a long narrow deformable tube at low Reynolds numbers is obtained. Pressure oscillations and tube deformation are shown to be related by an integrodifferential equation. The solution obtained extends the Poiseuille solution in elliptic tubes to the case of comparatively arbitrary small deformations in terms of the tube length and angle.
Keywords:
viscous incompressible fluid, Navier–Stokes equations, analytical solution, Poiseuille flow.
